' Toa'ZZ whom it mag "concern:

Be 't -known that I, BYRON B.- GOLDSMITH,

-' a citizen of the UnitedStates, residin at New York city, in the county of New} ork "5 and State of New York, have invented cer- 'vtain new and useful Improvements-in Com' positions of .Matter and Processes of Making the Same; and I do hereby declare the .following'toibea full, clear, andexact de- 'able" others skilled in the cart to which: it appertains tov make and use the same.

I have chosen these two amins as examplesv to show that not-' Withstandingv thegreat difference between- .Ithem, methyl aminbelng a gas and anilin ,a liquid, thefform'aldehyde compound of each .is :suitablehfor the reaction. ln..,he same manner EI'canuse the formaldehyde j compound of otheramins'such as ethyl amin;

propylamin', toluidin, xylidin, .etc.

It is to be understood that in the claims sion is intended to cover not onlyordinary resorcin, alphaand beta naphthol, pyrogallol, and ini'fact 'any compound of this" with the'methylenegroup of 'the com ound Y formed by reacting 'uponan a'min' wit for;

maldeh'yde, u-On :heating the compounds forn ed jasi aboyej described they become. harder, andmore insoluble, and they are well 'adapted for molding under heat and pres- ,substa'nces as'is well understood inthe art, and in fact, they can be. put to all the uses sure, with or without the admixture. of other liberated during the reaction can be partly or entirely removed at the proper stage, and

it is sometimes desirable to remove it and ,sometimes not, depending upon the properties desired in the final product. My claims I for the compound are independent of the particular process used in producing it, and of Whether or not the by-products (such as liberated amins) are incorporated.

I claim 1. The process of producing an artificial resin which consists in causing a phenol to Wreact upon a defin te formaldehyde compound of an amin While heating the combined materials, and continuing the process until a definitely resinous mass is produced.

2. The process of producing an artificial" resin which consists in causingcarbolic acid to react upon. a definite formaldehyde compound of an amin While heating the c0mbined materials, and continuing the process until a definitely resinous mass is produced.

' 3.. The process of producing an artificial resin Which-consists in causing a phenol to react upon 'anhydroformaldehydeanilin While heating the combined materials, and continuing the-process until a definitely res- .inous mass is produced.

4. The process of producing an artificial 7 Witnesses:

resin which consists in causing carbolic acid to react upon anhydroformaldehydeanilin While heating. the combined materials, and continuing the process until a definitely resinous mass is produced.

- 5. The process of producing an artificial resin which consists in causing a phenol to react upon anhydroformaldehydeanilin in the presence of heat, separating the anilin produced in the reaction from the remainder with ater, lOW electrical conductivity, and

the capacity for entering into solid solution in the product.

In testimony whereof, I ailiX my signature in presence of two Witnesses. 7
